number of people who believe it's happening has increased by, say, three percentage points over the last year, the number of people who think it is human caused has dropped. >> it has dropped dramatically. i mean, the statistics on this are quite incredible. 2007, according to a harris poll, 71% of americans believed that climate change was real, that it was human caused. and by last year, that number went down to 44%. 71% to 44%, that is an unbelievable drop in belief. but then you look at the coverage that the issue's received in the media. and it's also dropped dramatically from that high point. 2007, you know, this was this moment where, you know, hollywood was on board, "vanity fair" launched their annual green issue. and by the way, there hasn't been an annual green issue since 2008. stars were showing up to the academy awards in hybrid cars. and there was a sense, you know, we all have to play our part, including the elites. and that has really been lost.
